Reference to the detailed description which follows and which is dividedunder suitable headings will give a full understanding of the variousfeatures embodied in the present invention and their intended mode ofoperation.

For the purposes of illustration this invention has been shown asapplied to a type of machine, the general principle of which isdisclosed in the United States application, Ser. No. 263,125 filed Nov.19 1918 by Frederick L. Fuller as well as the British patents 135,465;157,823; 157 ,824 and 157,825 granted for the same invention, but it isto be understood that this invention is not limited to this type ofmachine, but may, with slight modifications from the presentillustrative embodiment, be applied to other well known forms ofaccounting machines.

Framwork The various parts of the mechanism are supported by a suitableframe work comprising a base casting and suitable side frames neither ofwhich are shown in the present drawings. The main side frames areconnected at their upper rear ends by a frame work 21 and crossconnections in the form of tie bars 22 and 23 situated toward the frontand rear of the machine respectively. The present machine is alsoprovided with two intermediate and parallel supporting frames 24 and 25shown in Figs. 3 and 6. The mechanism is enclosed by a cabinet 26preferably formed of one piece and may be made of any suitable material.The cabinet 26 has hinged thereto a fiat lid 27 and a front cover 27 forprovidingaccess to the printing mechanism for replenishing the papersupply, printing totals and resetting the totalizer.

K eye and operating mechanism.

The illustrative machine is provided with a number of groups of amountkeys, several of these keys being shown in Fig. 1 and indicated by thereference characters 28.

The amount keys 28 are pivoted upon a shaft 30 extending transversely ofthe machine and journalled between the side frames. The keys are guidedin their reciprocating movements by slots 31 formed in the front part ofthe cabinet 25 and are further guided at their rearward ends by avertically slotted plate 32 attached to the tie bar 23. Resting upon therear ends of the keys is a key coupler 34 journalled at 35 between theside frames. The key coupler has a nose 36 oo- 35 operating at timeswith notches 37 formed in the rear ends of the keys 28. When the outerends of the keys are depressed the key cou ler 34 is rocked clockwise(as viewed in Fig. 1) and the nose 36 thereon enters the notches 37formed in the rear end of the keys. The pur ose of such key couplermechanism is well known in the art and need not be discussed herein.

Connected to the key coupler at 38 is a vert cal reciprocating rackplate 39 provided with oppositely facing rack teeth 40 which alternatelymesh with a gear 41 fast to a main operating shaft '42 j ournalledbetween the machine side frames. The arrangement of this mechanism issuch that a reciprocation of the key coupler 34 by the keys will effecta complete rotation of the gear and v the shaft 42 to which the gear issecured. The

shaft 42 is provided with cams or other suitable devices for operatingvarious parts of the registering and printing mechanisms.

Dz'fierential mechanism is provided with an upwardly extending arm 43carrying an anti-friction roller 44 co-operating with differential slotsformed in cam plates 45. Loosely mounted upon the transverse shaft 46 isa frame 47 provided with spaced slots in which are secured by pins 48, aseries of cam plates 44, one for each key. The cam plates are providedwith L shaped slots 49 and 50, the slots 50 being concentric withrespect to the shaft 46. The slots 49 are, however, graduated so thatwhen the rollers 44 carried by the frame 47 of a depressed key operatesin the difi'erenti a1 slot of its associated cam plate 45 it will movethe frame 47 differentially and to an amount commensurate with the valueof the key depressed. When, however, the frame 47 is operated by thedepression of a key 28 of a certain group, the rollers 44 of theundepressed keys of the same group will play in the arcuate slots 50 oftheir respective cam plates 45, thereby permitting the frame 47 to beraised differentially without interference with the rollers 44 of theunoperated keys.

It is to be understood that there is a dif ferential frame for eachgroup of amount keys. As is shown in Fig. 1 the differential frame 47has attached thereto a segmental rack 51. In continuous mesh with theteeth of the segmental rack 51 is a pinion 52 attached to an item typewheel 53 mounted upon a shaft 541 and adapted to print upon a recordstrip. From the above it will be evident that since there may be ninekeys in a particular group and a corresponding number of cam plates 45the segmental rack 51 and type carrier 53 may be brought to any of ninedifferent positions by the depression of a key 28 associated with suchgrou of keys. In a manner similar to this the keys associated with anyof the denominational groups will adjust their related type carriers sothat when printing is effected the type wheel will print the charactercorresponding to the value of the keys depressed.

As best shown in Figs. 3 and 4 the machine is provided with threesegmental racks 51 for adjusting a corresponding number of amount typecarriers 53. There is also shown a special type carrier 54 forindicating the type of transaction entered in the machine. This typecarrier is normally in a position to print a character indicating a cashtransaction, but may be movable to other positions under the control ofspecial keys for indicating other types of transactions, such asreceived on account and paid out. For adjusting this type carrier'54differentially there is provided a segment 55 which is oper- Situatedbelow the type carriers 53 and 54 is a pivotally mounted totalizer'56.The

totalizer 56 as shown in detail in the Fuller application and generallyin- Fig. 1, is pivotally mounted between the side frames .24

at 57 and having mounted therein a shaft "58 supporting a series ofwheels 59. v v

In order to bring the totalizer 'pinions 60 which are secured to thetotalizer wheels 59 in mesh with the actuating racks 51 at the desiredtime, any suitable mechanism may be employed to attain this end and oneform which this mechanism might take isshown and describedinconsiderable detail in the' Fuller application #263,125 referred tohere inbefore.

Record strip printing mechanism It is desirable that each time an itemis entered in the machine that this amount be printed upon the recordstrip within the machine cabinet. The record strip provides thecompleterecord of all the transactions ens. tered in the machine, and at the endof an arbitrary period may be detached from the machine and filed awayfor future reference. The printing mechanism for printing the items andtotals accumulated by the totalizer 56 comprises a pivoted frame formedof two side plates .61 and 62 (Figs. 1 and 2) the lower ends of whichare provided with claws 63 engaging the shaft 46. Normallythe printingmechanism rests by its own weight 1n the position shown in the drawingswith lugs 64 contacting with a portion of the frame 21. The side frames61 and 62 are connected together by a cross member 65 as shown 1n Fig. 2and shafts and other members whlch will be referred to as thedescr1ption progresses. In the position shown the prmter frame isadjusted to print from the type carriers the items and other specialdesign atlons upon the record strip.

Journalled in the printer side frames 61 and 62 is a shaft 66, theextreme left end of which has fastened to it a bell-crank 67 carrying aroller 68 co-operating with the race .of a box cam 69 fast to the shaft42. As has been mentioned hereinbefore the shaft- ;42 is given acomplete rotation during each operation of the machine and the rotatlonof (A the box cam will rock the shaft 66 to actuate a platen and to feedthe record strip and ink-v ing ribbon an increment.

66 Extending transversely of the printer side frames 6l-and 62 is aplaten supporting shaft 70 (F1 3) upon which is supported the platen 1by means of forwardly extending arms 72 and 73 secured to the shaft 70.The

under face of the platen 71 is provided with a ruhber lmpression block-7 4 clearly shown in Figs. 1 and 2.

Fxtending rearwardly fro is actuated y a hammer 77 to force the platen74 against the type to take an impression. The platen 71 is not directlyconnected to the platen actuating arm 75, but is connected to it 'byaclutch member 751 (Fig. 3). The and 25 and comprises a h ame Journaned'as Iclutch member 751 is loosely mounted upon the shaft. 70 and isadapted to connect or disconnect the arm 75 with the arm 72 since it isprovided with a notch 78 adapted to engage with a rib 79 formed on oneside of the platen supporting arm 72. A spring 80 surrounds the shaft 70and is interposed. between a collar fast to the below the platen or forany other reason all that is necessary is to manually slide the clutch751 to the right asviewed in Fig. 3 to disengage the notch from thelocking rib and lift the platen frame upwardly...

For actuating the platen actuating arm 75 the hammer 77 is provided andis formed as part of an arm 81 pivoted to the inside right printer frame62 by a stud 83. The hammer 77 is forced upwardly by a spring 84 bearingagainst a lug 85 carried by printer frame 62. The arm 81 is furthermoreprovided with a spring pressed retracting pawl 86 having a tail bearingagainst an adjustable stop 87 on the arm 81. The pawl 86 has a lug 88cooperating with a nose 89 formed as part of an arm 90 secum to theprinter operating shaft 66 previously mentioned.

When the arm 90 is rocked clockwise by ,means of the bell-crank 67 andthe shaft 66 to which the bell-crank is secured the nose 89 will bearagainst the lug 88 of the pawl 86 and retract the hammer 77 against thetension of the spring 84. Upon further movement of from the adjustedtype carrier.

The record strip upon which are printed the items shown diagrammaticallyin Fig. 1,

v the paper extending from. the supply roll 91 around suitable guiderolls under the platen v and movable with the arm 72 is a platenactuating arm" .75 (Fig. 2 .provided with a lug 76 which 71 around otheruide rolls carried by the laten and finally ack to the storage roll 92.he details of the record strip as well as the means for advancing itduring the operation of the machine are fully set forth in theaforementioned application Ser. No. 263,125

and therefore need not be described.

The machine is further equipped with an inking ribbon and a ribbonfeeding mechanism which are not shown in the drawings since these do notcomprise any part of the present invention. One formwhich this mechanismmight take is clearly shown and described in the Fuller application Ser.No. 263,125 to which reference may be had for further details ofconstruction and operation.

It is suflicient here to state that the inking ribbon passes between therecord strip, below the rubber impression block 74, and the type wheels53.

The lids 27 and 27 which are hinged to the cabinet 26 are provided tocover and conceal the record strip printing mechanism and printingtotalizer. The lid 27 is provided for the purpose of permitting theclerk to obtain access to the paper holding mechanism in order toreplenish the supply of paper when it is exhausted while the lid 27'permits access to the totalizer printing means and the resettingdevices. These lids may be under control of different looks so thatwhile the clerk may have access to the printing mechanism forreplenishing the paper supply he cannot have access to the other deviceswhich would permit him to obtain information he was not entitled to.

Secured to the under side of the lid 27 there is a glass 91 (Figs. 2 and5) to permit the visibility of a number of items which have previouslybeen entered in the machine. The glass is, furthermore, cut away at 92to permit written entries to be made in juxtaposition to the printeditems in the manner shown in Fig. 5. As previously described the recordstrip passes over the upper surface of the platen 71 and this surfaceprovides a suitable writing table.

Ruling device Coming now more particularly to the present invention theillustrative machine is provided with a special printing device forprinting lines upon the record strip simultaneously with each itemprinting operation.

As is well known the autographic attachment for cash registers isprovided for the purpose of permitting more extended entries in the formof written notations to be made along with the printed item. If, forexample, the transaction should be one involving a paid out transaction,the clerk would write alongside of the printed number the reason theamount was paid out and in case a person paid a certain sum on accountthe clerk would write the name of the party alon side of the printeditem so that the book eepin or auditing department could readily ere itthe person with the amount paid. By this means the proprietor or managercan have full information regarding each transaction and by perusing therecord strip at the end of the day he can note what has taken place andbe able to check up at any time any transaction entered in the machine.

In some mercantile establishments oods are sold in quantities and it isdesirab e for the purpose of check or inventorying that the total of thequantities sold during a period be known. The autographic attachmentprovides a satisfactory means for the attainment of this end and permitsthe entering of quantities on the record strip so that at thetermination of an arbitrary period these may be summed up to determinethe total sold during this time. When notes, such as this, are placedupon the record strip it is found diflicult to keep the writtennotations of the different articles separated and divided. In order tofacilitate the summing up of the written amounts it is the purpose ofthe present invention to provide a ruling attachment so that parallellines may be printed upon the record strip simultaneously with eachprinting operation so that the notation may be entered in the propercolumn.

The mechanism for effecting the above is shown in Figs. 3 and 4. It willbe noted that the shaft 541 upon which are mounted the printing wheels53 and 54 passes through the side frame 24 and projects out somedistance. Loosely mounted upon the shaft 541 are a plurality of printingmembers 92 provided with slots 93 and printing edges 94 adapted toco-operate with the rubber impression block 74. A rod 95 which passesthrough the frame 24 and is rigidly held by the screw 96 so as toprevent any lateral movement, cooperates with the slots 93 and holds theprinting members 92 against movement. In order to suitably space theprinting members 92 at the proper distance there is provided a series ofsleeves 97 also mounted on the shaft 541.

The operatioh of the above described device is as follows: When themachine is operated by an operation of any of the keys the platen 74 isforced downwardly against the type carriers 53 and 54 and also againstthe ruling members 92 so that the printing edges 94 will print in ahorizontal line a series of parallel lines shown in Fig. 5. As is shownin this figure, the glass 91 is marked by etching or otherwise toindicate the proper columns on the strip for each particular class ofgoods sold so that the clerk may make the desired notation in the propercolumn. The embodiment shown illustrates how this system can be used ina gasoline station and shows a number of sales of gasoline and lubrioil.At the end of the day the numcatin %gallons of gasoline entered in thecolher 0 tank. In this manner a running inventory of the proprietorsstock may be kept and any attempt to defraud the proprietor maybereadily ascertained or prevented.

As shown in the drawings there is provided five printing members whichwill print a corresponding number of lines upon the record strip, butthe number of printed lines will, of course, depend upon thenumber ofarticles which it is desired to segregate as well as the system invogue. In order that the number of lines printed may be changed at will,the sleeves 97 can be made of various widths so that when it is desiredto make a change all that is necessary is to insert sleeves 97 of thenecessary widthso as to separate the printing members 92 the desireddistance. This, of course, is merely one means by which the printedlines, may be changed and any other means may be used without departingfrom the spirit of the invention.

If so desired the modification shown in Fig. 7 may be employed where itwill be seen that the printing elements 92 are slotted so as toco-operate with the rod 95 but are rigidly secured to sleeves or hubs101. The hubs are secured to a long sleeve 102 by set screws 103, thesleeve 102 in 'turn being loosely mounted upon the type wheel supportingshaft 541. Adjustability is secured by sliding the printing members tothe desired places and securing them at these positions by the setscrews 103. It is also apparent that the printing block can be formed soas to print any number of lines horizontally, vertically, or in anyother way desired, depending upon the requirements of the business.

As further modificationsof the present invention Fig. 6 shows a block 98which is screwed at 99 to the frame 24 and provided with printingelements 100 which are adapted to print four vertical lines upon therecord strip while Fig. 8 shows a ruling block 105 adapted to print ahorizontal line with each item printin operation. These ruling blocksmay be ma e up and kept in stock so that when it is desired to changethe style or number of lines or their spacing all that is necessary isto detach the old printing block and substitute a new one therefor.

It is to be understood that while an example has been given of one useof the machine as disclosed it is not intended to limit its applicationto the line of business for which it has been described herein.
